When the AC Hotel Marriott opens Friday in the Park Street entertainment district Downtown, it will further reinforce owner Chris Corso’s desire to become a serious restaurateur and real-estate developer. The 160-unit, 8-story hotel, built by local developer Continental Real Estate Cos., will have four Corso-owned food-and-drink destinations to open at a later date. Before his business went vertical, Corso was cutting his teeth in an emerging club scene. Corso’s early nightclub portfolio, with former business partner Mike Gallicchio, had its share of critics. That’s been true in the past year as well, with citations for COVID violations, accusations of biased policies and more. But Corso is less concerned with improving his image and more with forging ahead with upscale developments and restaurants, the new Urban Chophouse among them.
